Removing the Top Cover Warning
To prevent electric shock or system damage, before removing the chassis cover, must turn
off power and disconnect the unit from power source.
Electrostatic discharge (ESD) can cause serious damage to electronic components. Dry
climates are especially susceptible to ESD. It is therefore critical that whenever the product
is accessed internally, or any other electrical component is handled, the following anti-static
precautions are strictly adhered to:
⚫
Wear an anti-static wristband: Wearing a simple anti-static wristband can help to
prevent ESD from damaging the board.
⚫
Self-grounding: Before handling the board, touch any grounded conducting material.
During the time the board is handled, frequently touch any conducting materials that
are connected to the ground.
⚫
Use an anti-static pad: When configuring the product, place it on an anti-static pad.
This reduces the possibility of ESD damaging the product.
⚫
Only handle the edges of the PCB: When handling the PCB, hold the PCB by the
edges.
